Description

BACKGROUND OF THE INVENTION The present invention relates to a coin processing apparatus, for example, a coin processing apparatus installed in a coin handling apparatus such as various vending machines and coin deposit machines used in the financial industry.

The hardening processing device usually has a coin verification function that determines the authenticity of the inserted coin. If it is determined that the coin is not genuine, the coin will be returned to the return slot.
Alternatively, processing such as automatically checking the coin again is performed. Many electronic coin verification devices are used.

Some electronic coin validation devices include, for example, an oscillation coil and a pickup coil that are placed across a coin passage. Then, it detects the change in the induced voltage of the big eye when the coin passes between the two corners of the passage, and determines whether this change is within the required tolerance range. This allows us to determine the authenticity of coins.

Conventionally, this permissible range has been fixed, and a user or the like has not been able to easily change the permissible range from the outside.

However, users may want to change the coin verification accuracy depending on the situation, and therefore there is a demand for a coin processing device that can change the coin verification accuracy.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coin processing device in which coin verification accuracy can be easily changed by external operation.

The coin processing device according to the present invention determines the authenticity of a coin by determining whether the output level of a coin verification device including a detector that detects an amount representing the characteristics of a coin is within a required tolerance range. An input device for specifying data representing a desired tolerance range among the plurality of data stored in the means, and an output level of the coin verification device within the tolerance range represented by the data designated by the input device. The present invention is characterized by comprising an authenticity determining means for determining whether a coin is genuine or false by determining whether or not the coin is present.

According to this invention, it is possible to specify data representing a desired tolerance range from among the data representing a plurality of tolerance ranges stored in the memory element () stage using the input device. Therefore, even a user can easily change the coin verification accuracy by external operation depending on the situation.

For this reason, for example, automatic winding machines reduce coin verification accuracy during times when there are many users or when there are many users, and the rate of re-insertion of returned coins and re-verification due to genuine coins being mistakenly determined as counterfeit coins. Reduce processing time by reducing
Users will be able to freely perform tasks such as increasing coin verification accuracy when there are many counterfeit coins in tB@.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 shows a schematic structure of a coin deposit machine. The coin deposit machine (1) has a coin input hopper (2) and a carrier (3).
), coin sequential feeder (4), coin validation device (5A) ~ (5F

Coin passage (9) ~ αη between people) ~ (6F) and +71
is formed. A coin passage (a flapper 08 for sorting) is provided at the place where the passage Q31 and the circle diverge from 12+.

The carrier (3) is normally located at the inserted coin receiving position shown by the solid line, and the carrier (3) is placed in the hopper (2) [which transports the inserted coins to the coin passage (
9). After sending out all the inserted coins to the passage (9), the machine moves to the return coin receiving position shown by the chain line 3A.

The progressive feeding device (4) feeds the coins sent through the passage (9) one by one into the passage (101) at appropriate intervals. Large denomination sorting holes are made at predetermined intervals in descending order of diameter.In this example, 1 yen, 50 yen, 5 yen, 10 yen
There are holes for sorting the denominations of 0 yen, 10 yen, and 500 yen. The coins sent to the passageway (+01) fall into the passageway (11) from the denomination sorting hole corresponding to the denomination. In other words, the coins cannot be sorted into denominations depending on their size.

The coin verification devices (5A) to (5F) detect the material of the coins sent through the passageway (11).

Inside the coin validation device (5A) to (5F), there is a passage 0!1 for guiding the coins sent from the passage 01) through the passage (12I).
(See Figure 2) is formed. The control device (8) controls the above-mentioned parts, and also controls the coin verification devices (5A) to (5F).
) is used to determine the authenticity of coins and perform coin counting processing based on the detection signals. For sorting, the flapper 0η is always in a position that closes the passage Q31 of the passage (131043), and the coins that have passed through the coin verification devices (5A) to (5F) are determined to be genuine by the control device (8) I. is activated to open passage 0:1 and close passage 04) for a certain period of time. Therefore, coins judged to be genuine pass through passage 0 and are temporarily stored in storage areas (6A) to (6F).
＋This will be sent. Coins determined to be counterfeit are stored in aisle A4Ja.
After passing through n, the authenticity determination of all returned coins and input coins is completed, and each coin is sent to the temporary holding section (6A) to (6F) or the carrier (3A) according to the result of this determination. If the deposit is not canceled, the carrier (3A) is returned to the inserted coin receiving position, and the coin determined to be a counterfeit coin is returned. Or, if necessary, the coin verification process is performed again on these coins. Temporary holding section (6A) ~ (6F
) are sent to the storage section (7)E through the passage α9 after the coin verification process is completed or when the next customer inserts the coins.

If there is a cancellation of the deposit, the temporary holding section (6A) to (6
F) The coins being held are in the aisle (161 (17)
After that, the carrier (3A) is returned to the input coin receiving position ζ. All coins inserted will be returned.

FIG. 2 shows the internal configuration of the coin verification device and the control device. The coin validation devices (5A) to (5F) are provided with an oscillation coil (211) and a pickup coil @, which are arranged facing each other across the passage 09.An oscillation circuit (23)
When an alternating current is passed through the oscillating coil (21+1), an alternating magnetic flux is generated, and the pick-up coil (22H
This voltage is induced. This induced voltage is amplified by an amplifier circuit (incorporated) and then sent to a detection circuit (c), where high-frequency components are removed. □The output voltage (to) of the detection circuit (2) based on the induced voltage of the pickup coil @ takes a constant value (VO) when the coin does not pass between the coils (211C77J) as shown in Figure 3. , when the coin is passing between coil C11 (24), Sl, 82, S
It decreases as shown by 3. Output voltage (V) cD minimum (i & (VSl) (VS2) (V
